SX1250IMLTRT

SX1250IMLTRT is a multi-band sub-GHz RF front end. It is designed to work along with Semtech’s SX1302 baseband engine, to design a high-performing LoRa® or LoRaWAN gateway. It covers any frequency band below 1GHz, making it the perfect candidate to support any license-free band used in today’s IOT use cases. The device supports up to +22dBm output power on-chip. This embedded high-power capability can be leveraged to reduce the bill of material cost when designing a gateway. As far as receiver, the Noise Figure of the system is also extremely low, eliminating the need for an external high-end and power-consuming Low Noise amplifier, if the goal is to come up with a cheaper and median-spec gateway. Application includes LoRa® and LoRaWAN gateways.
